Suggested Roof Pitch

One engineer recommends a 12 12 pitch for the new roof while another recommends a 7 12 pitch.

Suggested roof pitch.

The ibhs recommends a 4 to 6 pitch roof. Roof pitch is often expressed as a ratio between rise and run in the form of x 12. Pitches lower than 4 12 have a slight angle and they are defined as low slope roofs. This is for the top level of a 3 story building that is 26 by 64.

The roof pitch would be described as a 6 12 pitch. Roof pitch is simply the slopecreated by the rafter. The most commonly used roof pitches fall in a range between 4 12 and 9 12. This measurement is best done on a bare roof because curled up roofing shingles will impair your measurement.

It can be assessed in two ways either as the angle the rafter makes with the horizontal or the proportion between the rise and the run of the roof. The pitch of your roof also helps determine the type of materials that can be used on your roofing system. Understanding a roof s pitching can be quite tough if you are just getting started and working with a roofer can leave you a little bit unsure about what is being suggested with regard to the job there s so much to learn that it can become a bit baffling. The picture below shows the pitch of a 7 12 roof slope meaning that for 12 of horizontal measurement roof run the vertical measurement roof rise is 7.

Pitches of less than 2 12 are considered flat roofs even though they may be very slightly angled.
